IMPROVEMENT IN SEED-DRILLS.

Specification forming part of Letters Patent No. 31,105, dated January 15, 1861.

To all whom it may concern:

Be it known that I, J. H. BEAN, of Forreston, in the county of Ogle and State of Illinois, have invented a new and Improved Seed-Drill; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being bad to the annexed drawings, making a part of this specification, in which- Figure 1 is a side sectional view of my invention,taken in theline mrc,Fig.2; Fig.2, atransverse vertical section of the same, taken in the line y y, Fig. 1; Fig. 3, an inverted plan of the same; Figs. 4 and 5, detached sectional views of the two hoppers, taken respectively in the planes 2 z z 2', Fig. 1.

Similar letters of reference indicate corresponding parts in the several figures.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a rectangular frame, which is mounted on Wheels or rollers B B, and has a drivers seat, 0, placed longitudinally upon it. The rollers B B are placed on separate axles a a, and are therefore allowed to rotate independently of each other.

On the back part ofthe frame A there is placed. a cross-bar, b, said bar being directly back of the rollers B B, and having two V- shaped scrapers, attached one directly back of each roller. The form of the scrapers is shown clearly in Fig. 2. By referring to this figure it will be seen that the scrapers are formed of quite narrow metal bars, and by referring to Figs. 1 and 3 it will be seen that the scrapers are curved corresponding to the curvature of the rollers, and the outer edges of the scrapers are in contact with the rollers or are quite close thereto.

To the front end of the frame A there is attached by pivots c c a frame, E, which is allowed to work freely on its pivots c c. On the frame E there are placed two seed-hoppers, F G. These seed-boxes extend the whole width of the frame F. 7

.ln the seed-hopper F there is placed a shaft, H, which is armed with radial teeth 11. This shaft is rotated by a belt, e, from the axis of one of the rollers B. The bottom of the hopper F is formed of a perforated metal plate, d, underneath which perforated plates 0 e are placed, the central one, 6, being'allowed to'slide longitudinally to form a register to regulate the escape of the seed:

To the under side of the hopper F there are attached vertical tubes f, each tube being in line with a perforation of the plate (1. The

bottom of the tubes f are connected to the back ends of curved bars 9, the upper and front ends of which are attached to the front end of The bottom of the hopper G is formed of twoparallel metal plates, 70 70', one of which, k, is secured permanently to the bottom of the hopper. The other plate, It, is connected to plate 70 by parallel arms I l, the ends of which are pivoted to both plates. This arrangement admits of the plate It being moved longitudinally and at the same time in a direction toward and from the plate is, so that the space between the two plates 70 70' may be increased or diminished in width, as may be required. The lower ends of the rods h pass between the two plates It It. To the front part of the frame E the draft-pole M is attached.

The hopper F is supplied with wheat or other grain, and the hopper G is supplied with grassseed. The grain, as the machine is drawn along and the shaft H rotates, is discharged through the perforations of the plates d c, the discharge being regulated by adjusting the lower plate, 6. The curved bars g serve as cutters to penetrate the soil and cut through all trash and weeds which may lie in their path,

the lower ends of the tubes fmaking neccssary drills to receive the seed. The grass-seed. is distributed from hopper G, the reciprocating rods h insuring its discharge between the plates 70 k, and in greater or less quantities. as may be desired, by adjusting the plate In the desired distance fromplate k. The grassseed is sewn directlyin front of the grain, and both are covered by the rollers B B.

The V-shaped scrapers D D,in consequence of being constructed as shown, effectually scrape the dirt from the rollers B B. The dirt cannot clog or choke the scrapers, as is the case where the solid-plate scrapers are used.

I do not claim the stationary and adjustable perforated plates 01 e at the bottom of hopper F, for they have been used nor do I claim the rotating toothed shaft H in the hopperF; but

I do claim as new and desire to secure by Letters Patent 1. The arrangement of the independentlypivoted frame A and rollers B with the frame E, seed apparatus F G H J K, tubes f, and curved. bars 9, as and for the purpose herein shown and described 2. ,In combination with the above, the employment of the curved V-shaped scrapers D upon the rollers B, as and for the purpose herein shown and described.

J. H. BEAN.
